To all whom' it may concern.-

Be it known that I, Dnwrrcr G. Anrrronv, oi the city and county oi Philadelphia and State of Pennsylvania, have invented a new -and-useful Improvement in Apparatus for Distilling Fresh Water from Salt es; and ido hereby declare the following to 1e a clear and exact description or the nature thereof, sutficient to enable others skilled in 'the art towhich my invention appertains to fully understand, make, and use the same, reference being bad to thc'uccompauying drawings, making part of this specification, in which- Figure 1 is a side elevation of the device embodying my invention. Fig. 2 is a trans? verse section in line a: a, Fig. 1. Fig. 3 is a top or plan view.

My invention consists in acondensiug-apparatusespecially designed for producing pure and fresh water, which may be used for various purposes. A boiler supports a condensing-chamber, and from the chamber passes a feed-pipe which communicates with the boil' or, and from the boiler passes a steam-pipe which communicates with. a coil or worm in the condensing-chamber. A filtering chmn'ber is arranged. between the steam-pipe and coil or worm, to prevent impurities entering the latter. Between the boiler and condenser is a space for preventing the heat of. the boiler reaching the condenser. .A pot communicates with the worm and has a perforated bottom or strainer for holdipg articles to be cooked, or otherwise treated, by the hot water or steam from the coil, the whole forming a convenient and portable condensing apparatus, which may be carried together in one, and is espe cially designed for ship-board, the-boiler to be supported on an ordinary stove or other heating apparatus, and the condenser supported on the boiler, the condenser also supporting the filtering-chamber.

Referring to the drawings, A represents the boiler, on which is supported the condensingchambcr B, which communicates with the boiTi r .A by means of a feed-pipe, (J, \vhiclfis provided with astop-coch, .2. Within the condensingchamber, 'B there is arranged a worm or coil, B, one end of which communicates with a conical or other shaped vesseL-E, at the upper end oi the chamber B, and its other end passes out of said chamber B, as at b. F represents a pot, which is adapted to be fitted on the outer end of the worm D and to communicate therewith. G represents a supply-pipe leading into the condensing-chamlwr B, and H represents a waste-pipe leading from said chamber B. The boiler A will have a gage'coclr, J, and blow-off cock K. Lreprc senfs a bottom, which is secured to the lower end of the chamber B'below the bottom proper 0 thereof, so that a space, d, is left between the two bottoms, and communicating with saidspace is a pipe, M, which opens into the atmosphere. Leading into the boiler A. is'a steenrpipeJ, which opens into thc vessel E, so as to form a commuilication between the boiler A and worm l), the top of said vessel being closed by a cap, a, and the interior oi the vessel having a strainer, f, for preventing impurities and improper substances passing into the worm, a filtering material beingplaced within said vessel E on the strainer f:

The operation is as follows: The water from a tank or place of'supply is passed iiito the chamber B through the pipe G. If the water is to be converted into steam. heated or distilled, the pipe H will be closed, and the stopcock at of the pipe 0 opened. The water then enters the boiler A, which is placed. over a suitable furnace, stove, or other heating appa- "ratus, and when the water reaches the gageeock J the stop-cock a may be shut off. The steam that is formed in the boiler rises in the pipe N, and is directed to the vessel E, from whence it enters the worm D, and, owing to the 'cool water surrounding the worm, the steam is condensed, and the-water of conden sation escapes at the outer end but the-w0rm, and may there be collected, thus providing a supply of'pnre and fresh water. This operation may be repeated as long as required. In the event of employing salt water the suit that settles may be blown out ot'the boiler through the cock K. lt' desired, a pipe, g, may communicate with the boiler and support a fog-horn, so as to sound alarm or signa-Lin bottom proper oi the'eoudensing-clmmher, so

eases of fog. The pot F has a pipe, h, which I is to be attached to the end 0 of the worm, jaull a strainer, k, on which will be placed (0f fee, tea, or other article of food or drink, so 1 that the pure water, passing from the worm, \rillact on the articles and subject them to the boiling or heating eti'ects of the watt-r. The space d, between the bottoms L 0, prevents the heat from the boiler 'n-achiug, the

that the water surrounding the worm niilnot be heated from the boiler, but the bout that radiates through the additional bottom 1. into said space d will escape through the ipe M into the atmosphere.

, Haviugthus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The boiler A, cotnlensing-chamher ii, and worm D, in combination with the filteringn'essel E between the steam-pipe and condensing worm, substantially as and for the purpose set forth.

2. The combination, with the boiler A, of the condensin x-chamber B, provided with the two bottoms L c, and the pipe M, COIIilflllHleating with the space between the bottoms, substantially as and for the purpose set-forth.

o. The boiler A. and condensing-chamber 8 supported thereon, in combination with the filtering-vessel 13 supported on the condensing-chamber, and interposed between the Stimuli-pipe N and condensing-worm D. substantially as and i'orthe purpose set forth.

4. The combination, with the condensingworm l), of tilt' pot 1- attached thereto, and communicating therewith. and ha-viiig a perforated bottom or strainer. K, substantially as and for the purpose set forth.
